" A planet is a wanderer which hasn't set in any place, like a moving light that is seen but nobody knows a thing about it"
The Greeks spoke in this way about planets because they thought the stars were stopped and the planets were another type of strange stars which moved without attending any norm.
All of this makes me think about our importance in the Universe. Were we significant, why would live in a simple wanderer, one like the others? Not only that, in the latest decades have been discovered more and more galaxies and an incredible number of planets. So, my thoughts are clear, more civilizations must exist apart from us.
However, we can't know more about that. Life is a consequence of the different combinations of carbon, but this is only a simple answer. If you ask a scientific, they would tell you about the vital functions: "growth, movement, reproduction, respiration, nutrition, and excretion" but what this means? It looks like life is all that want to live and last in time. But in these terms, the entire universe is alive for me. It grew up in the Big Bang, now is spreading out, there is a chance of the existence of other dimensions which may attend the evolution laws (I will talk about this in another post). Moreover, there are stars which are constantly fed up with hydrogen and they excrete helio and other elements. In addition to this, the Universe breaths energy, this is its oxygen.
The Universe could be a living being, and also, it is probably that other forms of life (made or not with carbon) exist, and they may live in our Solar system, in our Galaxy, in another spot of the Universe but also in other dimension or in the own Earth.
But I think that we are committing a big mistake when we talk of life in this way. Our real desire is to find out intelligent life, that is to say, a life which is capable of reasoning, questioning, like us, our true cause of being in the Universe. Life under these conditions may be found but is surely less abundant. Or maybe no... Who knows.
